Four Port Link Aggregation on Linux:

modprobe bonding mode=* miimon=100
ifconfig bond0 hw ether randommacaddress
ifconfig bond0 10.103.0.13 up
ifenslave bond0 eth0
ifenslave bond0 eth1
ifenslave bond0 eth2
ifenslave bond0 eth3

I won’t even get into the simplicity of Solaris’ persistent configuration vs. Linux’s persistent configuration – which will change between distributions, even.

The more I play with Solaris and OpenSolaris, the more I’m forced to admit that Linux is a mere toy compared to either.

Three commands and link aggregation just works. No hassle. No debugging. No conflicting instructions on how various bits should be configured. No trying to figure out what mode to use, or why your selected mode isn’t working despite the fact that it should.

It’s unfortunate Solaris requires a logical method of thinking. More people should be using it. The learning curve is supposedly steep – I dare say it is, when you’re used to the nonsensical environments of Linux, Windows or even OS X. Do yourself a favor and try to get past that.

Once you start discovering why things are so obviously set up the way they are, you’ll pause, perhaps scratch your chin, and say, “Damn – why the hell isn’t that other operating system like this?”

Naturally, replace #.#.#.# with the IP addresses of your nameservers.

/etc/sysconfig/network:
NETWORKING=yes
HOSTNAME=BOX
DOMAIN=DOMAIN.FOO

HOSTNAME is, of course, where you put the hostname of your box. This should not be a FQDN; the domain should end up in the DOMAIN variable.

/etc/sysconfig/network-scripts/ifcfg-eth0:
DEVICE=eth0
BOOTPROTO=static
IPADDR=172.16.42.142
NETMASK=255.255.255.0
NETWORK=172.16.42.0
BROADCAST=172.16.42.255
GATEWAY=172.16.42.1
ONBOOT=yes

This assumes the IP of your box is 172.16.42.142 with a netmask of 255.255.255.0. Network and broadcast will be set up in the same fashion, using .0 at the end of network and .255 for broadcast. Gateway may fluctuate depending on your own network setup – usually, gateways are located at .1, but your mileage may vary.

/etc/init.d/networking restart

…And yer off.
